In the polymeric title compound, {[Cd(C8H12N6)(H2O)4]SO4}n, the CdII atom is located on an inversion center and coordinated by four water molecules and two 1,4-bis(1,2,4-triazol-yl)butane ligands in a distorted CdO4N2 octahedral geometry. The 1,4-bis(1,2,4-triazol-yl)butane ligand is centrosymmetric, the mid-point of the central C—C bond being located on an inversion center. It links adjacent water-coordinated metal atoms into polymeric chains running along the c axis. Adjacent chains are linked by O—H...N hydrogen bonds. The S atom of the sulfate anion is located on a twofold rotation axis, thus the sulfate anion is equally disordered over two sites. The sulfate anion links with the polymeric chains via O—H...O hydrogen bonds, generating a three-dimensional supramolecular network.
